For car owners, a visit to an auto repair shop can cause as much anxiety as a trip to the dentist. Who knows what unforeseen problems will turn up? It’s the reason finding a reliable, honest mechanic – someone with your best interests in mind – is so important to car owners, especially those with little knowledge of the workings of a car.So how can car owners find such a car repair shop and ensure they won’t be taken advantage of? Fortunately there are a number of things you can do to find a mechanic who will provide reliable advice and honest quotes.Research auto repair shopsBefore you even leave the driveway, you first need to do some research. Ask friends or family to recommend a car repair shop in your area. Ideally, you will want to find a mechanic who is located close to you so it’s convenient to take your car in for repairs. Query friends who own similar autos on their experiences with mechanics. Friends typically like to offer advice, and they are more trustworthy sources than any claims of “best shop in town” by a repair shop.You can also conduct searches online on review sites such as Yelp and the Better Business Bureau, which offers an accredited list of businesses. You can also explore car-specific sites, such as Car Talk, which has a listing of mechanics reviewed by the NPR show’s online community. Google offers ratings of shops as well. Of course, it’s important to take online reviews with a grain of salt because issues and expectations can differ with each individual.Another way to check out a potential auto mechanic is to search for any investigations or complaints about their work. For starters, many state attorney general offices investigate auto repair shops and keep a database of complaints. You can find your state AG office online and search for complaints against the shop you’re interested in using. If your state AG office doesn’t handle automotive repair shops, see if your state consumer protection agency has a database on auto mechanics.Check for credentialsThere are other concrete things you can look for that will help you decide which repair shop to visit. “The first thing we like consumers to do is determine whether it’s a licensed repair facility,” says Joseph Henmueller, president of the Automotive Maintenance Repair Association. He cautions motorists to avoid mobile operators and individuals found on Craigslist who offer bargain rates. “If anything goes wrong, they’re not licensed by the state, and consumers have no recourse.”Also, look for certifications and accreditations with auto repair licensing organizations. Besides Henmueller’s association, others include ASE (Automotive Service Excellence) and iATN (International Automotive Technicians Network). “Look to see if they have an AAA association, and have ASE technicians in their shop,” Henmueller saysMake sure the technician assigned to work on your car is certified for your specific problem. ASE certifications require separate tests for different parts of a car, such as brakes or transmissions. “You want to know if the guy working on your brakes is ASE certified in brakes,” Henmueller says.Ask for documentationWhen trying to find an auto repair shop, it’s also important for the shop to have a process in place to provide written documentation for each step of the transaction. Your initial concern should be documented, and customers should get written reports of any inspections and estimates before any work is started, with separate line items for parts, labor, taxes and fees. And parts should always be identified as new, rebuilt, remanufactured or used. At the same time, whatever warranty is offered should be printed on or attached to the invoice. A typical minimum warranty is three months or 3,000 miles.Another sign of a reputable shop, Henmueller says, is a policy that offers to return any replaced parts to the consumer, or at least to make them available for inspection. “If you replace four tires, you want to be able to see the tires before they send them to recycling,” he says. “It gives you some assurance that parts were taken off and new parts put on.”Do an in-person visitBefore committing to a mechanic, you should visit in person to get a look at the shop itself. If the shop appears to be unprofessional or in disarray, that may be an indication of how your car will be treated. “If there are indiscriminate cars pulling up delivering parts, they could be coming from a junkyard,” Henmueller says. “Professional organizations look, sound, smell and feel professional. If it smells funny, it is funny.”See where you can save moneyGoing to a repair shop shouldn’t put a dent in your wallet. When shopping around for a mechanic, it’s important to keep in mind:

Stick to the owner’s manual recommendations. Most manuals lay out a lifetime maintenance plan to keep your vehicle running reliably with minimal repairs and costs.

Finding an independently owned center or small chain may save you money in the long run. If your vehicle isn’t under warranty, you’ll generally pay less there than at a dealership. In exchange for your loyalty, you may also get a few perks, such as preferred appointment times or a discount on routine oil changes.

If there’s been a recall or technical-service bulletin, your repair may be done free at a local dealership. Check the maker’s website for recall notices before you book an appointment at a service center.
